Suppose k and l are fixed numbers. since the following are lines with different slopes, the graphs of the two lines y=18x+k and y=5x+l must always intersect somewhere. find a formula, using k and l, for the intersection point. say how you found the formula.

Contd.

Explanation:

We will use the following well-known

Result : The eqn. of a line l passing through the pt. of

intersection of the lines l1:a1+b1+c1=0andl2:a2x+b2y+c2=0 is of

the form

Result :

from the figure we get,

the x axis shows   the months and,

the y-axis shows the number of satisfied customer.

each line or each cell in upward direction (y-axis) shows 500.

the appropriate scale for the y - axis is: -

a = 2000 customers

b = 4000 customers

c = 6000 customers

d = 8000 customers

e = 10000 customers

f = 12000 customers

g = 14000 customers

a
